Anti-Malware — entry 014 of 15
VirusTotal
VirusTotal aggregates verdicts from dozens of antivirus engines and threat-intel sources to score files, URLs, domains, and IPs, exposed through a JSON REST API (v3, jsonapi.org-flavored) that also powers its web UI. A live GET against api/v3/ip_addresses/8.8.8.8 with an invalid x-apikey header returned 401, reconfirming API-key auth over HTTPS, and two separate OPTIONS preflights against the same endpoint returned no Access-Control-Allow-Origin header, resolving cors to no. The public API is free for individual/non-commercial use, with a paid Premium/Enterprise tier for higher quota and additional threat context.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
